REFRIGERATING DEVICE.

To all whom it may concern:

Be it known that I, MARK E. STOVER, a citizen of the United States,residing at Detroit, in the county of lVayne and State of Michigan, haveinvented a new and useful Ice-Making and Refrigerating Device, of whichthe following is a specification.

My invention relates to improvements in the freezing-tanks ofrefrigerating and icemaking machines; and the objects of my improvementare: first, to provide a continuous, positive and rapid circulation of acooling medium, such as brine, around each ice-can in the tank so as tofreeze the contents thereof with the greatest possible rapidity; second,to provide an ice-making and refrigerating device in which the amount ofbrine circulating around each icecan shall be substantially equal intemperature and rapidity of circulation throughout the entire tank, thusproducing a uniform freezing of the contents of the ice-can; and third,to provide an ice-making tank which shall be composed of compartments soconstructed that the cooling medium may be cut off from any desirednumber of the said compartments without affecting the balance of thetank. I attain this object by the device illustrated in the accompanyingdrawing, in which a perspective view of my improved device is shown.

A represents the outer wall of the freezing tank, of any desiredconstruction. The tank is divided into a plurality of compartments bylongitudinal partitions B and transverse partitions C. These partitionsmay. be joined to the bottom and sides of the. tank in any desiredmanner, such as by riveting or soldering, but their tops aresufliciently lower than the outer walls of the tank to permit the brineto rise and flow over the partitions without overflowing the tank. Eachcompartment is adapted to receive an ice-can, D, supported in anydesirable manner such as by bars E, placed near the bottom of eachcompartment. It is desirable that the cans should be of such depth that,when placed in position in the compart ments, the tops of the said cansshall be sufficiently above the tops of the said partitions to permitthe flow of brine over the said partitions without allowing it to flowinto the cans. The cans are of sufliciently smaller dimensions than thecompartments in which they are placed to allow the brine Specificationof Letters Patent.

to circulate around them on all sides. The brine is supplied to thelower part of these compartments by a series of pipes F, with suitablenozzles Gr so placed as to admit the brine, at the center of eachcompartment and below the ice-cans. A pump H forces the brine throughthe pipes into each compartment, compelling it to rise around the cansand to flow over the tops of the partitions into the brine-cooler I atone side of the tank. Here the brine is cooled by suitable means, suchas flowing over cooling pipes J and is drawn from the lower part of thecompartment I by the brine pump H, thus making a positive, complete andrapid circulation around each ice-can.

By making the longitudinal partitions somewhat higher than thetransverse partitions, it is possible to divide the freezing tank into aseries of batteries; and by providing the pipes of the circulatingsystem with suitable valves K, the brine may be cut off from any numberof batteries Without affecting the operation of the balance of the tank.

I claim:
